Project Description: The Sonoma-Marin Area Rail Transit District (SMART) is a Special District within the State of California that owns, maintains, and operates passenger rail service in Sonoma County and Marin County. In addition to passenger rail service, SMART is a common carrier that owns and operates freight rail services within Sonoma County, Marin County, and Napa County.
SMART is seeking Sealed Bids from qualified, experienced, and licensed contractors to replace two existing timber railroad bridges (Basalt Creek MP 29.31 and San Antonio Slough MP 31.74) with steel open deck bridges on steel piles and precast abutments and wingwalls. The replacement bridges are longer than the existing bridges and are to be installed behind existing abutments and headwalls, which are to remain in place. Both of these railroad bridges are located on SMART's Mainline and on active railroad right-of-way. SMART will provide one (1) weekend shutdown of the railroad in order to set the bridge decks for both bridges. Besides this authorized shutdown, continued railroad operations is critical throughout the duration of the project.
